SPECIFICATION formingpart of Letters Patent l\To. 665,361, dated January1, 1901.

Application filed May 10, 1900.

T at whom, it may concern.

Be it known that I, JOHN W. BERRY, a citizen of the United States,residing at (513 North Cakes street, in the city of Tacoma, in thecounty of Pierce and State of \Vashington, (and whose post-officeaddress is Tacoma. Washington,) have invented a new and usefulImprovement in Automatic Weighing-Mar chines, of which the following isa specification.

My invention pertains to devices for weighin articles of merchandisepreparatory to trade and commerce.

It pertains more particularly to improvements in my newly-inventedautomatic weighing-machine for which application for Letters Patent wasfiled February 27, 1900, Serial No. 6,708.

The objects of my improvement are to simplify the construction of mymachine and to provide an automatic electrical means for operating thesame. I attain these objects by means of the apparatus illustrated inthe accompanying drawings, in which Figure l is a side elevation of mymachine constructed with my newly-invented improvement. Fig. 2 is a leftfront view of the same.

Similar letters refer to similar parts in both views.

My invention comprises a wide wheel W, constructed with a number(preferably five) of triangular-shaped buckets between the sides ordisks B and C, which, with the webs forming the triangular apartments,form the construction of the weighing-wheel. The wheel is mounted on theaxis A between two upright supports G G, each of which is rigidly fixedto a base or platform F, designed to rest on the scales H. The uprightsupports G G continue up till above W and support the chute L, pivotallymounted at a. This chute is designed to receive material from thesupply-chute D and fill each bucket of the weighing-wheel with an equalweight of the same, all of which is fully set forth in my formerspecification. As each bucket is filled with the required weight ofmaterial the wheel turns automatically and discharges each regularlyinto the discharge-chute E. The wheel during the filling of each bucketis held in serial No. 16,138. lNo model.)

equilibrium by the spring R, acting on the lugs d to (Z and the weightedarm S, resting on the lugs e to 6 alternately. The friction of thespring R and of the adjustable spring brake-beam N, acting 011 theprojecting pins g to 9 cause the wheel to revolve steadily and to stopwithout jolting as each bucket comes into place to be filled.

My improvement comprises a small pivoted latch-hook I), mounted on oneside of the swinging chute L. As the wheel W revolves this latch catcheson the lugs 61 to d and draws the chute forward against the edge of theshelf M until each bucket is filled in its turn.

0n the shelf Z is provided an electric battery X, and on the shelf M isan electromagnet Y, properly connected with the battery, to be chargedtherefrom. One pole of the battery is connected by wire 19 to thescale-beam J at p. The opposite pole, by means of the wire it, isconnected with the adjustable key at directly above the scale-beam J.

\Vhen one of the buckets, as No. 1, receives the desired weight ofmaterial, the scale-beam tips up and, coming into contact with the keyit, the circuit is closed, causing the electro magnet to attract the endof the lever-arm t', pivotally mounted at Z. The opposite end of i isconnected bymeans of the adjustable wire 713 to the latch-hook b, whichis now instantly lifted, relieving the lug d, and allows the wheel toturn forward and bring bucket No. 2 into position. As soon as No.1begins to empty into E the scale-beam tips down again and the circuit isbroken, the electromagnet relieves the lever i, and the latch-hook I)again drops down in time to catch lug 61 and thus hold bucket No.2 inposition until filled. In this way my machine can be operated conotinuously for any length of time and Weigh the quantities rapidly andaccurately.

By means of my improvement my machine is simplified in its construction,and being made in one combination complete in itself 5 it can be placedon any form or size of scales and operated without a special frameworkto adjust it thereto.

1 am not limited to detail in my electrical attachment, but retain theright to vary the form and proportions to best suit the size andcharacter of my machine to obtain the desired result in the mostpractical manner.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-- 1. An automatic weighing-machine,comprising in combination with the scales, the rotary compartment-wheel, a pivoted feedin gchute, a pivoted latch mounted on saidchute, the free end of which latch is disposed in the path of theprojections about the circumference of said wheel, an electromagnet, andelectric circuit adapted to be closed when a predetermined amount of material is weighed in one of the compartments of said wheel, and saidlatch raised out of the path of said projections as the circuit isclosed, as set forth.
